What Is Spray Booth Filter Media? Structure, Types & Working Principle

1. What is Spray Booth Filter Media?

Spray booth filter media is a specialized dust filtration material used in spray booth systems and industrial painting rooms. Its primary function is to capture paint particles, prevent air pollution, and ensure high-quality paint finishes. The filter media helps control dust and contaminants during the painting process, thereby enhancing product durability and aesthetics.

2. How Does Spray Booth Filter Media Work?

Spray booth filters operate based on mechanical and electrostatic filtration principles. When air containing dust and paint mist passes through the filter layers, the polyester or fiberglass fibers trap the particles through:

• Multi-layer deep filtration: Interlaced fiber structures effectively capture dust from the outer to the inner layers.

• Clean airflow output: After filtration, the air released is cleaner, helping maintain a controlled environment inside the spray booth.

3. Types of Spray Booth Filter Media

Currently, there are three common types of spray booth filter media available on the market:

a. Ceiling Filter

• Used to filter incoming air.

• Captures fine and ultra-fine dust particles before entering the spray booth.

• Made from compressed fiberglass or polyester fibers.

b. Floor Filter / Exhaust Filter

• Filters paint mist and exhaust air before releasing it into the environment.

• Designed to withstand high air pressure and offers long service life.

c. Pre Filter

• Installed at the air intake to capture larger dust particles.

• Helps extend the lifespan of finer downstream filters.

4. Frequently Asked Questions (FAQs) About Spray Booth Filter Media

Q1: How often should spray booth filters be replaced?
👉 Typically, filters should be replaced every 3–6 months depending on usage frequency and contamination levels.

Q2: Can spray booth filters be reused?
👉 Most spray booth filters are single-use to maintain optimal filtration efficiency. Washing and reuse are not recommended.

Q3: What sizes are available for spray booth filter media?
👉 Available in various sizes, with common widths of 1.6m and 2m, and thicknesses ranging from 15mm to 50mm. Custom sizing is also available.

Q4: How can I tell if the filter is clogged?
👉 Signs include reduced airflow, visible paint build-up, or you can check the pressure drop across the filter to determine replacement time.
